External Helical Gear Mesh Contact Analysis - April 29, 2021
Who Should Attend
Gear design engineers who are interested in developing state of the art competitive gear designs which provide optimized power density. Gear mesh loaded contact must be evaluated and improved using helix and profile modifications to achieve the assumed load distribution factor which has been applied in gear life and rating calculations. Loaded tooth, shaft and bearing deflections cause tooth mesh contact to shift, reduce in size and concentrate causing the potential for premature gear tooth fatigue failure. This course would be of interest to experienced gear manufacturing engineers, inspectors, quality assurance and operators to better understand the complex helix and profile modifications called out on high performance, optimized gear drawings.
- Identify the need for contact analysis and describe the theory behind the contact analysis process
- Model the loaded gear mesh shafts, bearings and gear geometry in commercially available dedicated gearing “FEA” software to calculate magnitude and direction of tooth deflections and deformations.
- Develop tooth profile and helix modifications that compensate for tooth deflections, reducing transmission error and optimizing power density
- Describe the tools and processes of contact analysis
- Review cantilever pinion example of contact analysis and corrective action
- Review non-symmetrical bearing mounted shaft pinion example of contact analysis and corrective action
- Present contact analysis Do’s and Don’ts
